Description
In this talk I will discuss a new approach to classical general relativity.
Currently, most analytical methods to general relativity are inherently perturbative, while Numerical Relativity remains computationally expensive. I will present a middle path: an exact renormalization group (RG) equation for classical gravitational systems. The equation correctly reproduces the Post-Minkowskian expansion, while also easily recovers the 1PN two-body action, bypassing the need for complex three-graviton vertex calculations. I will then show how the equation can be derived from the classical limit of the Polchinski equation, demonstrating its exactness. This establishes the exact RG as a powerful new tool for tackling strong-field dynamics in gravity.
